Reactivity of s-block metals increases on moving down the group. What about halogen's reactivity on moving down the group
Options:
Answer:
B
Solution:
Halogen reactivity Decreases down the group. This is because atomic size increases, and the outermost electrons are further from the nucleus, reducing the effective nuclear charge and electron affinity. Halogens gain electrons to react, so a lower electron affinity means lower reactivity.
